Edit Doom 3's doomconfig.cfg to boost performance by adjusting image cache and disabling bump mapping.

Walkthrough
  1. 1
    Locate the doomconfig.cfg file.
  2. 2
    To improve game performance, you can edit the following settings:
    • Set image_useCache to "1".
  3. 3
    Set image_cacheMegs to 1/4th of your system's memory.
  4. 4
    Calculate image_cacheMinK using the formula: image_cacheMegs / 8 = n, then n * 1024 = image_cacheMinK.
  5. 5
    To disable bump mapping and potentially gain a few frames per second (FPS), you can change the following settings:
    • Change image_filter from GL_LINEAR_MIPMAP_LINEAR to GL_LINEAR.
  6. 6
    Change image_anisotropy from "1" to "0".
